It took him a long time to think of the reason.
"Please, I forgot 'Now I lay me'."
"Will you say it to me, right here at my knees?"
Bobby climbed out of the bed, knelt by the lady, laid his head on her knees and repeated the sleep-forgotten prayer. He looked up when he had finished and found the lady had covered her face with both hands. Perhaps she was saying her "Now I lay me," and Bobby kept still for a long time. Finally he squirmed around for another look at the train of cars.
The lady must have known that he was through, for he felt gentle hands on his shoulders.
"Who taught you that?" she asked.
"The 'tendant with the blue and white dress."
"It's—it's beautiful," said the lady in a voice that sounded very much like Bobby's when he had water in his eyes.
He looked up and saw there was water in her eyes! Suddenly he felt queer inside and knew something without having been told.
